Enigma emulators
http://www.attlabs.att.co.uk/andyc/enigma/enigma_j.html
http://www.izzy.net/~ian/enigma/applet/index.html
Two excellent emulators that show how the Enigma machine works. The former allows you to alter the machine settings, but it is not possible to track the electrical path through the scramblers. The latter has only one setting, but has a second window that shows the scramblers moving and the subsequent effect on the electrical path.
